Patented Mar. 25, 1930 STEPHEN v. DILLON, or TULSA, OKLAHOMA, Assrenon o SMITH snrARATon COMPANY, A CORPORATION 012 OKLAHOMA ROD OR TUBING- GUIDE My invention consists in new and useful improvements in sucker rod and tubing uides for use in pumping oil wells, and has for its object to provide a device, which may be easily inserted in the well tubing and automatically maintain itself in the desired position by frictional contact with the inner walls of-said tubing, permitting the sucker rod to slide freely up and down therethrough, but

limiting its lateral movement, thereby preventing said sucker rod from coming in contact with the walls of the tubing during its pumping strokes. 7

Another ob 'ect of my invention is to provide a rod guide which may be easily removed in case of rod breakage, and to this end, I provide a series of fishing lips on the outside ofthe body member of the device, at its upper extremity.

A still further object of my invention is to provide a guide having .a channel, bell mouthed at each end, to facilitate its engagement with a rod. 1

With the above and other. objects in view which will appear as the description proceeds, my invention consists in the novel features herein set forth, illustrated in the accompanying drawings, and more particularly .pointed out in the appended claims.

3a Referring to the drawings, in which numerals of like character designate similar parts throughout the several views,

Fig. 1 is a view in side elevation, Fig. 2 is a view at right angles to Fig. 1,

showing the device in place on a sucker rod within the well tubing,

Fig. 3 is a plan view of the device, showing the tubing in dotted lines, I 1

Fig. 4 is a view in side elevation of a modi- 40 fied form of my device, adapted for'use as a tubing guide, showing the well casing in section, and j r I Fig. 5 is a plan View of thesame, The preferred form of my invention, as

constructed foruse as a sucker rod guide, comprises a ma1n body portion 1, conslstlng,

. of two half sections 2 and 3, the adjacent inner faces of which are grooved longitudinally to form a central channel 4, when said sec- 4 5e tions are secured together. This channel 4 is bell mouthed at each end, as clearly shown in dotted lines at 5 and 6 in Fig. 2, for the purpose hereinafter set forth.

Along the adjacent edges of each section 2 and 3, I provide laterally projecting flanges or webs 7, apertured centrally to receive bolts and nuts 8, whereby said sections 2 and .3 are clamped together. On opposite sides of the main body portion 1, and .at right angles to the webs 7, 1 provide laterally projecting lugs 9, which extend outwardly from the center of the body portion,"substantially the same distance as the webs 7 for purposes hereinafter described. A

10 represents a plurality of bowed spring members, rigidly secured at their upper ends to the body portion 1 of the guide, by screws 11, or other suitable means, said spring members being free at their lower ends, and ex- I tending outwardly a suficient distance to frictionally engage the well tubing 12, as clearly shown'in Fig. 2. The upper end of the body member 1 is provided with a series of circumferentially body portion, instead of consisting of two sections, is an integral structure, somewhat larger in diameter than the rod guide. This 7 device, instead of being inserted within the tubing 12, surrounds said tubing and frictionally engages the inner walls of the casing 16, serving as a tubing guide. The other fea tures of this modification are practically the Y same as the device heretofore described, with the exception that instead of employing the lugs 9, I provide a series of webs-17, which extend substantially-the entire length of the body member, said webs being spaced intermediate the spring membersl I I The use and operation of .rnyimproved ui e easf l ev The rod guide is applied to the rod 14 at any point between the box and the pin, the sections 2 and 3 being secured together by the bolts 8 to slidably retain said guide in place on the rod. As the rod is lowered into the well, the springs 10 on the guide immediately come in contact with the inner face of the'tubing, and the guide is momentarily stopped until the pin 15, which, as before stated, is of larger diameter than the balance of the rod, comes in contact with the upper end of the guide, when the weight of the rod overcomes the resistance of the spring 10 against the inside of the tubing, and the guide is forced downwardly into the well. This is repeated as many times as there are guides applied to the string of rods.

After all of the rods are in the well, and set on bottom against the standing valve, the pin is naturally at its extreme low level. The rods are then raised to eliminate the stretch, which lifts the pin 15 off of the rod guide, said rod guide being held in place by "than the rod, said rod is permi'ted to work the friction between the springs 10 and the lnner face of the tublng where 1t is retained in a stationary position. After the string of rods is hooked on the power above the casing head, the pin 15 never reaches the guide again, and as the channel 14 through the mside of the guide is of larger diameter freelyt-hrough the guide without lifting or lowering the same, the friction of the spring 10 against the inner face of the tubing preventing the guide from going up or down.

It will be noted that due to the series of outwardly extending lugs and webs on the body member of the guide, said guide substantially fills the tubing, and maintains the rod inspaced relation ,to the tubing, thus eliminating wear between the rod and tubing, yet at the same time, as will be seen from Fig. 3, providing sufficient fluid space around said guide. 7

In case a rod should break at such a point that it would fall through the guide member,

the operator may easily insert the proper fishmg tool in the tubing, and when said tool comes in contact with'the upper end of the guide, the latter will be pushed downwardly of the other section of the rod. Vith the bell mouth of the channel 4 adjacent a broken section of rod, it is obvious that when the guide ispushed downwardly, the rod will naturally 5 find itsway into the inside channel of the guide, and the latter pushed downwardly, out

of the way of the fishing tool, so said tool can secure a hold on the upper end of the rod.

As before stated, the fishing lips l3 are provided on the upper end of the guide member to facilitate the removal of this member from the tubing when desired.

It is well known that there is a certaini amount of vibration in the well tubing when becoming out of alignment, I have provided the modification shown in Figs. 4 and 5, the operation of which with respect to the tubing, is practically identical with that just described, with respect to the rod. 7

It is obvious that my improved guide may be employed with the rod alone or with the tubing alone, or with both rod and tubing.

From the'foregoing it is believed that my invention may be clearly understood without further description, it being borne in mind that changes may be made in the details disclosed without departing. from the spirit of the invention as expressed in the claims.

What I claim and desire to secure by Letters Patent is:

1. A rod guide adapted to be inserted in a well tubing, comprising a body portion having a channel therethrough for slidably engaging sucker rod, a plurality of diametrically opposed rigid projections on said body ertion for maintaining the same centrally of aid tubing, and a plurality of bowed. springs on said body arranged to frictionally engage the walls of said tubing in advance of said projections for automatically retaining said guide in a stationary position at the desired said body porticn to points just within the inner circumference of the well tubing,

whereby said guide is maintained substantially centrally of said tubing, and spring means directly below said lugs and at right angles to said flanges for automatically retaining said guidein a stationary position at the desired 7 depth in said tubing.

3. A rod guide for use in well tubing, comprising a body portion provided with a fishing head.

4:. A rod guide as claimed in'claim 3, wherein said fishing head comprises a series of fishing lips. r

5. A rod guide for use in welltubing, comprising a body portion provided at its upper end with a series of circumferentially extending, superposed fishing lips.

In testimony whereof I aflix my signature.
